Mailing List Archive: 0xfor 3. Parser bug?

This was just posted on SO

https://stackoverflow.com/questions/67083039/why-does-python-return-15-for-0xfor-x-in-1-2-3

I can reproduce it with a simpler example

>>> 0xfor 3
15

Is it a bug in the parser, or working as intended? It's not only for
hex. This works to

>>> 3or 50
3

Kind regards,

Stefano Borini

It is already discussed in thread >

It does not contradict specification, but looks pretty confusing, so we
will likely change specification and implementation to prevent confusion.
